Constrain the degree of freedom such that a particular node is dependent on the behavior of another node.

Constrain the behavior of one node to the behavior of another node. Define the main node that affects the deformation of another node and degree of freedom [Constrained Node/DOF]. TX, TY, TZ are the degrees of freedom for displacement and RX, RY, RZ are the degrees of freedom for rotation. [Independent Node/DOF] inputs the coefficient applied on the displacement of the independent node, to define the degree of freedom and interrelationship between the dependent node.

Boundary Set

Register the set constraint conditions on the desired boundary set. The user can specify the name of the boundary set.

The behavioral characteristics are similar to Mesh > Element > Create > Other > Rigid link. For example, when the main node moves by a certain distance, the dependent node can be constrained such that it moves by twice that length. When creating a complex interrelationship between two or more nodes, the constraint equation can be used.
